te D-dimer ka puta mai i te paheketanga o te fibrin, he pūmua ka uru ki te whakaheke toto.

I te wa e pupuhi ana te toto, hei tauira i te wharanga, ka piri etahi o ona kaihanga ki a ratou ano, ina koa me te awhina o te pūtōtepe.

Ki te kore e rawaka te whakaheke toto, ka puta te toto ohorere (whakaheke toto). I te anga ke, ka he nui, ka taea te hono ki te hanganga o nga toto tera pea he hua kino (deep vein thrombosis, pulmonary embolism). I roto i tenei take, ka whakatakotoria he tikanga whakamarumaru hei whakaheke i te taikaha fibrin me te whakaheke ki nga kongakonga, ko etahi he D-dimer. Ka taea e to ratau aroaro te whakaatu i te hanganga o te toto.

Ka tohuhia e te taote he whakamatautau D-dimer mena ka whakapae ia kei te puta te toto. Ka raru pea enei, penei:

• a thrombosis uaua hohonu (i huaina hoki phlebitis hohonu, ka puta mai i te hanganga o te katinga i roto i te kupenga uaua o nga peka o raro)

• pulmonary embolism (kei te kitea he toka karekau he arai pulmonary)

• he ranei patunga

Ko te inenga o D-dimers ka mahia e te tauira toto venous, i te nuinga o te waa ka mahia i te taumata o te kopa o te tuke. I te nuinga o nga wa ka kitea e nga tikanga immunological (whakamahi i nga antibodies).

Kaore he whakaritenga motuhake e hiahiatia ana.

Ko te kukū o te D-dimer i roto i te toto he iti iho i te 500 µg / l (micrograms ia rita).

Ko te whakamatautau D-dimer he nui te uara matapae kino. I etahi atu kupu, he hua noa ka taea te whakakore i te tohu o te thrombosis uaua hohonu me te embolism pulmonary. I tetahi atu taha, ki te kitea he tiketike te taumata o te D-dimer, he whakapae kei te noho mai he kowhatu e tohu ana i te thrombosis o te uaua hohonu, te pulmonary embolism ranei. Ko tenei hua me whakamana e etahi atu whakamatautau (ina koa ma te atahanga): na reira me ata whakamaori te tātaritanga.

He pono kei te piki ake te taumata o te D-dimer kaore e pa ana ki te aroaro o te thrombosis vein hohonu me te pulmonary embolism. Kia whakahua tatou:

• hapūtanga

• mate mate

• mate toto

• te resorption o te hematoma,
• tata nei te pokanga

• mate mumura (pērā i te rheumatoid arthritis)

• he tawhito noa ranei (neke atu i te 80)

Kia mahara ko te whakatau i nga D-dimers he tikanga tata tonu (mai i te mutunga o nga tau 90), a ko nga paerewa kei te noho tonu te kaupapa o te patai. No reira i Parani, kua whakatauhia te taumata kia iti iho i te 500 µg/l, engari i te United States kua whakahekehia tenei paepae ki te 250 µg/l.
